What’s the difference of Modem and Router
We are going to talk about the difference between a modem and a router. Because many people think that a modem and a router are the same. But they are not, they differ from each other with two separate roles in a network. So I’m going to explain the difference between the two.
Now if you want internet within your home or business you need a modem, a modem brings internet to your home or business modem establishes and maintains a special connection with your internet provider. To give you access to the internet now is the reason why you must have a modem because of the two different types of signals that are used on one computer and on the Internet a computer only reads digital signals while signals are transmitted on the internet or analogue. Analog data comes from the internet; the modem d modulates the incoming analog signals in a digital signal, so that a computer can understand it and a modem too modulates outgoing digital signals from a computer into an analogue signal when it goes out on the internet and this is where we get the word modem. The word modem means modulator demodulator what exactly is what a modem does, it modulates outgoing data from a computer and demodulates incoming data from the internet. Now a router comes in after the modem.
There are different types of routers. There are routers that are used in companies and larger organizations. And there are smaller routers that are used in homes and small businesses. But they basically do the same. We will use the small office / home office router that most of us are familiar with. Now a router is the route or passes your internet connection to all your devices in your home or the company will send it to all phones from tablets, and so on so that those devices can access the Internet a Typical small offices / home offices such as these have a built-in switch with multiple ports. So you can connect multiple devices use an Ethernet cable connection. And it also functions as a wireless access point, allowing wireless devices. Such as tablets and laptops can have internet access.
Technically, you really do not need a router if you just want one of your devices to access the internet. You can simply plug the network cable from that device directly into the modem and then you can access the internet however like most houses and businesses. You will have multiple devices that need internet access, and that is where you would need a router. There are also different types of modems and two of the most common types are cable and DSL modems. So depending on the type of internet you are going to use, you must use the correct type of modem.
Cable modems are connected to your home using a coaxial cable. The cable is usually supplied by the same company that provides you with cable television such as Telenet, one of the largest providers in Belgium and DSL modems are connected via a normal telephone line DSL is supplied by companies such as Telenet, the largest provider in Belgium? Now very often your internet service provider. When they send you a modem, or if you would buy one in the store? The modem may be a modem router combination so it will be a modem with a built-in wireless router in one physical device. Like this here So here is an example of different networks about how they connect to the internet. This network on the left, for example, uses a cable modem. And it uses a small office / home office router. So that the computers in the tablet have access to the internet.
On a bottom we have a different network and this network uses a DSL modem and it also uses a small office / home office router so that it’s the computers the laptop and the computer. Tablet has internet access. The network on the right is an example of a corporate network. And it uses a cable modem and uses a business router so that we can connect his computers and his server. Finally we have the network here and this has only one device that needs internet access. It does not have to use a router, it can simply connect directly to the modem, because only one device is needed internet access. Now, if you are wondering how hubs and switches are Relates to routers and modems. Keep in mind that most routers have a built-in switch. You do not need to use a switch if you already have a router with a switch built in. For example, a router like this can have a four port Integrated switch so you can connect four Ethernet cables for your wired devices. So the only time But maybe you need to add a switch to this network if you need more wired connections for your devices. So you can simply connect a switch to your router and add more connections to the switch. So to make things even clearer here, we have internet with all its routers. The internet is then routed to this private network. It first reaches the modem, then it goes from the modem to its router with its integrated switch And then it is passed on to all of his computers.
